ShellExecuteEx在部署机器上不执行任何操作。

问题描述

大家好，



我有一个奇怪的问题，我希望有人可以帮我解决这个问题。



在以下C ++代码示例中：

Hi all,

I''m having a strange issue and I hope someone could help me on this one.

In the following C++ code sample:

OFLOG_INFO(logger, "Auto open PDF report feature enabled. Launching pdf viewer for file: " + rData.getPDFFileName());

// It is apparently recommended... See MSDN references.
CoInitializeEx(NULL, COINIT_APARTMENTTHREADED | COINIT_DISABLE_OLE1DDE);

SHELLEXECUTEINFO ShExecInfo;
ShExecInfo.cbSize = sizeof(ShExecInfo);
ShExecInfo.fMask = NULL;
ShExecInfo.hwnd = NULL;
ShExecInfo.lpVerb = (LPCSTR)"open";

// a small trick to cast from string to LPCSTR
char fileNameCast[MAX_PATH];
sprintf_s(fileNameCast, "\"%s\"", rData.getPDFFileName().c_str());

ShExecInfo.lpFile = (LPCSTR)fileNameCast;
ShExecInfo.lpParameters = NULL;
ShExecInfo.lpDirectory = NULL;
ShExecInfo.nShow = SW_SHOWDEFAULT;
ShExecInfo.hInstApp = NULL;

if(! ShellExecuteEx(&ShExecInfo))
{
	OFLOG_ERROR(logger, "Error during pdf auto-opening. Error Code: " +  int(ShExecInfo.hInstApp));
	OFLOG_ERROR(logger, GetLastError());
	somethingWrong = true;
}

我尝试使用默认的PDF阅读器自动打开PDF文件。



这个代码在我的开发计算机上就像一个魅力，但是一旦我在测试机器上部署我的应用程序，就没有任何反应。 I可以从日志中看到代码执行没有任何错误但只是没有...



我现在正在调试这几天而且我'我很确定我错过了一些愚蠢的东西。我希望有人能看到它。请参阅MSDN参考



注意测试机器安装了pdf阅读器（Adobe Reader）并设置为默认值。在开发和部署机器上运行OS是Windows 7。我还尝试使用更简单的函数完全相同的结果。



先谢谢你的帮助。我真的很感激。

Yass。

I try to automatically open a PDF file with the default PDF reader.

This code works like a charm on my development computer but as soon as I deploy my application on a test machine, nothing happens. I can see from the logs that the code is executed without any error but just nothing...

I''m debugging this for a couple of days now and I''m pretty sure I''m missing something stupid. I hope someone can see it. See MSDN reference here.

Note the test machine has a pdf reader (Adobe Reader) installed and set as default. Running OS is Windows 7 on both development and deployment machine. I also tried with the simpler function ShellExecute with exactly the same result.

Thanks in advance for your help. I really appreciate.
Yass.
